#[unsafe(no_mangle)]pub unsafe extern "C" fn nemo_relay_register_subscriber(
    name: *const c_char,
    cb: NemoRelayEventSubscriberCb,
    user_data: *mut c_void,
    free_fn: NemoRelayFreeFn,
) -> NemoRelayStatus

Register an event subscriber. The callback is invoked for every lifecycle event emitted by the runtime.

Parameters

  • name: Unique subscriber name.
  • cb: Event callback. The FfiEvent is valid only during the call.
  • user_data: Opaque pointer passed to cb.
  • free_fn: Optional destructor for user_data.

Safety

name must be a valid C string. cb must be a valid function pointer.
